NAVIGATION: To make your life easier, and help you find exactly what you want, we have broken the on-line equipment catalogs into smaller sections. Just CLICK on the item you are looking for at the left, to see the matching catalog. Large graphical catalogs are a bit SLOW, so please give them a bit of time to load. The top header of each catalog is largely the same, so don't think you are stuck in one place!

You can order anything here just by picking up the phone, and calling (250) 769-1834 during normal office hours, 8:30AM to 4:30PM PST, or FAX to (250) 769-4106. OR, Email your order to Susan HERE.

E-Mail Susan if you want a quote for shipping to other destinations, or for something heavy. Sorry, we can't safely send most individual small parts in a regular letter envelope, they get destroyed by the automated handling equipment. Sometimes we can ship very rugged parts in a small padded envelope by letter post. Ask Susan.

There is a packing charge for large or heavy equipment, see the FAQ for details.

If we have your valid data on file, you can just click on the ORDER email link to place an order and indicate your approval to bill, and we will do the rest. We keep your active information for ONE YEAR for your convenience.

If this is the first time you have dealt with us, you can phone +1 (250) 769-1834 or FAX +1 (250) 769-4106 to supply the billing info, or send it by the email link, as you prefer. We accept VISA/MC, international money order, Paypal (to Susan@Okanagan.net), and bank wire transfer. Please note that there are transaction fees with Paypal and wire transfer payments, the wire transfer fee is frankly horrifying, $50.

CONDITION: We have both new and used tubes available, many factory new in original packaging. Other than inpesction, we cannot electrically test most of these tubes, and must be sold as-is.

The CATALOG will appear below shortly!Don't forget these illustrated sections take a few seconds to load, but they are worth the wait!

WE NEED THE SPACE, WE HAVE TO CLEAR OUT THESE BULKY BOXED TUBESGreat for lab experiments, schools, etc., they all have connectors for bias networks (can be common for many tubes) and some output pulse forming networks already installed

PICKER new Picker 13538Y assemblies with standard 11 pin keyed PMT socket (for type 931A or sim.) with voltage divider. Use as much or as little as you want of this assembly with your PMT, very handy for experimentation, easily disassembled. Nice enclosed socket assembly made from a AN/MS3102/3106 connector shell, can be screwed into a chassis connector shell with no insert. Very limited quantity available. hard socket to find, sorry, no wiring data available.

Hamamatsu used but very good condition 13 pin miniature PMT socket complete with electrode resistor array voltage divider and output coax cable. A great way to quickly get your PMT up and running and mounted. For R647 style tubes. Violet is -HV, coax is the output, black is ground. Like new, known good lab spares. Cables approx. 14 inches long. E849 PDF data sheet HERE.

Hamamatsu used but very good condition 13 pin miniature PMT socket complete with electrode resistor array voltage divider and output coax cable (most have a coax connector attached), with mounting ears. A great way to quickly get your PMT up and running and mounted. For R647 style tubes. Violet is -HV, coax is the output, black is ground. Cables approx. 2 feet long. E849 PDF data sheet HERE.

Premium beige based (non-hygroscopic) tubes, 70's manufacture, VERY HARD TO GET! New in mil white boxes and RCA boxes, some are JAN types. Same outline and base diagram as 931A, but much higher sensitivity.

Sylvania (not RCA as shown) vacuum photodiode, S-4 response photodetectors, sim. to 929 but very low dark current and improved base. Very hard to find now, highly in demand for physics instruction. New in factory boxes.

1P40

GE Photodetector (side sensing)Gas photodiode, S-1 response, similar to 930, but with lower dark current and improved low water absorbtion base. New old-stock 70's boxed GE parts, all tested for zero dark current and 1uA output under light.

Hamamatsu Side viewing tube and bias assembly, includes light masked tube, aluminum mount, socket, HV cable and bias assembly. Appear to be new (still in factory boxes), but may be removed from something as there are some dabs of pink paint. Supplied as-is.

Hamamatsu Side viewing PMTs, new old stock, also has ES stamped with the main part number. 70's tubes, unused and dark stored. Red enhanced bi-alkali photocathode, 185 to 750nm response (curve 451U), 410nm peak. 1250V max. excitation, 1KV typical. Double the sensitivity of the 931A, same socket and interconnect.

Hamamatsu side view all glass PMT, 12 pin . New, still in original factory bags, but old stock (1974). Special tube, no public data avaiable from Hamamatsu. Strictly as-is condition, due to age of the tube. Re-boxed for light protection.

RCA gas photodiode, S-1 response photodetector, very common tube used in older motion picture projectors. All unused RCA factory boxed (dark stored). Same curves as 1P41, terminals per 1P29. We have been out of stock for a while, but finally got some nice tubes in stock.

Used, from working equipment, great for lab experiments, includes mating cable connector. Excellent condition, dark stored. Popular scintillator tube, same performance as XP2102B, 9575KB and 9957KB. Basic tube data is HERE.

Hamamatsu hexagonal end viewing 2 inch multi-stage tube, with HV divider and signal amplifier assembly and sping loaded mount, and special window. Used, very good condition. Very handy for experimenters that want a ready-to-go PMT assembly. Factory data is HERE.

We have NEW sockets, and used socket assemblies for these. They are 19 mm, round, 10-stage, quartz window, UV-sensitive (160-650nm / 420nm peak), fast tubes. Also has Philips number, 9301 069 50003 (9301-069-50002). See FULL PDF DATA HERE from Photonis!

Hamamatsu The R5600U is a super-compact photomultiplier tube in an OPTO-8 package. The bialkali photocathode is 8 mm in diameter and the outer PMT diameter is 16 mm. The metal channel eight stage dynode allows for a very small over-all package which can be used where no other PMT can fit. Gain is 3 x 10^5 at 800V and a peak quantum efficiency of 15% (at 400 nm). These include the Hamamatsu E5780 voltage divider base assembly, which is described in the data sheet below. Risetime, falltime and pulse width are approx. 650, 1050, and 1500 psec. Transit time spread of 280 psec FWHM at 800 V with a single photoelectron event, response time of the PMT is 0.65 ns. Spectral range is 300-650nm, Bialkali photocathode. FULL R5600 PDF FACTORY DATA IS HERE. These are all excellent condition known good pulls, look like new.
